🧭 Three Core Doctrines Woven Into Every Resource

#1 — JUSTIFICATION: Grace-Centered Theology

At the heart of all of Scripture is the redemptive message of God’s saving grace to sinners in Jesus. Theologically, we call this justification, which is the hub of the theological wheel to which every passage and doctrine is connected. This grace message is the oak from which every acorn of biblical text falls and must be related in order to be properly understood and applied. This is why Mustard Seed Discipleship is committed to grace-centered theology. 

"The doctrine of justification by faith through the substitutionary sacrifice of Christ is very much to my ministry what bread and salt are to the table. As often as ever the table is set, there are those necessary things. I regard that doctrine as being one that is to be preached continually, to be mixed up with all of our sermons.”
- Charles H. Spurgeon, Sermon #3488, October 9, 1870

#2 — ADOPTION: Grace-Focused Identity

Every human either will find his or her core identity in a self-achieved righteousness or in a gift-received righteousness. We will functionally live as spiritual orphans trying to make a life and name for ourselves, or we will live like adopted and beloved sons and daughters, with all the freedom, peace, hope, and joy that flows from such an identity. The implications are manifold and wide-ranging, touching on practically every area of life.  This is why Mustard Seed Discipleship is committed to grace-focused identity.

“Adoption is the highest privilege of the gospel. The traitor is forgiven, brought in for supper, and given the family name. To be right with God the Judge is a great thing, but to be loved and cared for by God the Father is greater.”
— J.I. Packer

#3 — SANCTIFICATION: Grace-Empowered Transformation

What now? Should I expect to experience a spiritual change in my life? If so, how does that take place? What is my role in the process?  As Jesus says in John 15, “No one can produce good fruit apart from me.” Practically speaking, this means that we experience the fruit of the Spirit as we consciously abide in the Vine of Jesus’ imputed gift-righteousness. As the Spirit fills us like sap through a vine into a branch, we receive new motives and a new ability to manifest the new life of love, peace, patience, kindness, etc. This is why Mustard Seed Discipleship is committed to grace-empowered transformation.

“It is by simple, close, and searching views of the cross of Christ that the Spirit most effectually sanctifies the believer. This is the true and great method of gospel sanctification! Let no man dream of true mortification of sin, or real sanctification of heart, who does not deal constantly, closely and believingly with the atoning blood of Jesus.”
— Octavius Winslow, The Work of the Holy Spirit (129)
